Since the Global Polio Eradication Initiative（GPEI）was launched with a resolution of the World Health Assembly（WHA）in 1988

the global incidence of poliomyelitis had fallen by over 99%

leading to the post-polio era.In2013

the World Health Organization（WHO）developed The Polio Eradication and Endgame Strategic Plan（2013-2018）to wipe out poliomyelitis.The use of oral poliomyelitis attenuated live vaccine（OPV）has been reported to induce rare cases of vaccine-associated paralytic poliomyelitis（VAPP）and vaccine derived poliovirus（VDPV）-related cases.Therefore

an important approach to eradicating polio is to develop even more effective vaccines.Inactivated poliomyelitis vaccine（IPV）

which can avoid VAPP and circulating VDPVs（cVDPVs）-related events associated with the use of OPV

is indicated for most populations.However

the type and immunization schedule of polio vaccines vary across different countries.This article will summarize the current prevalence of poliomyelitis and updates on immunization strategies

which may provide a theoretical basis for polio eradication.
